Make a thick paste of wheat flour by mixing with salt and water. Boil
the potato, smash and mix with pepper powder and turmeric powder and keep
aside. Make balls with the wheat flour mix and spread them as chappathi
on a slab. Spread the potato mixture uniformly over the chappathi and
fold the chappathi into four folds. Spread that again in a triangular
shape. Apply oil on both sides of the chappathi and roast it on a hot
kadai.
